sonon r. alum, or uonawx, 'rsnnssss acnmmm-eas emaa'roa To a whom it mag concern:

Be it known that I, SOLON P. HAUN, a citizen of, the United States, residing at Mohawk, in the county of Greene and State of Tennessee, have invented certain new and useful Improvements in Acetylene-Gas Generators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same. a

This invention relates to new and useful improvements in acetylene gas generators and the primary object of the invention is to provide a generator of this type that is antomatically operated to control the amount of gas formed thereby.

another object of this invention is to provide a device of this character which is provided with a safety attachment whereby any excess volume of gas that is formed in the generator may be easily carried 011' without any danger, or in any Way interrupting the operation ofthe device when the gas pres sure has returned to normal.

Still another object of this invention is to provide an acetylene gas generator of this character which is provided with means for lifting and holding a carbid hopper that is disposed on the top of the gas bell in raised position, so that the same may be-easily refilled. l

A further object of the invention is to provide a device of this character which is simple and durable in construction, inexnsive to manufacture, and one which will ve .eflicient in operation.

Wi these and other objects in view, the invention consists of the novel features of construction, and the combination and arranginent of parts which will be hereinafter referred to and more particularly pointed out in the s iication and claims.

The accornpanyiin, drawing represents a central vertical section of the tank, bell, and carhid hopper of my invention, showing also the pipe frame and accessories in elevation.

In describing my invention I shall, refer to the drawing in which the numeral 1 desigmites the water tank of my improved generator which may he of any desired shape and which is formed preferably with downwardly sloping side portions 2 which'have secured thereto andprojecting upwardly an annular portion 3 that forms between the edge of the tank and the same the conven- Specification of Letters Patent.

\ Application filed l'ebruary 2 8, 1917. Serial No. 151,09;-

tional type of water seal that is commonly used. in devices of this character.

The water tank 1 is provided with a sloping bottom 4 which has at its lowermost polnt an outlet 5 through which the water may be easily drained when it is desired to empty the tank. This outlet 5 is provided a with any type of valve as clearly shown in the drawings. I

Positioned through one side of the inwardly projecting side portions 2 of the water tank is an agitator 6 which comprises a rod 7 having a handle 8 at its outer end, the said rod being positioned through a sleeve or casing 9 that projects upwardly from the tank. Securedto the lower end of the rod 7 is any desired type of agitator 10. By the above described construction, upon movement of the handle 8, the rod 7 wil be rotated and consequently the agitator 10 secured to its lower end will stir the contents ofthe tank.

The water tank 1 is provided with a transversely extending pipe 11 that has its 0 posite ends projecting from the said tan and connected with the opposite ends of this pipe are vertical upright parallel ipes which are designated by the numera s 12 and 13. These pipes 12 and 13 have their lower ends secured to the projecting ends of the transversely extending pipe 11 by suitable connections. The pipe 13 will be called the service ipe and the pipe 12 the volume out at pipe as they perform the aforesaid functions.

The pipes 11 and 12 have positioned in the upper ends of the same plugs 14 to prevent gas escaping through the pipes. The upper ends of these pipes are connected bya cross member 15 which comprises two sections wardly at right angles thereto and then upwardly to a point above the water level of the tank. This pipe forms a connection be tween the gas generator and carries them to the transverse pipe 11 by which means it is carried from the tank. The branch inlet pi e 18 is provided at its first angle with a at head 19 for a urpose to be hereinafter more fully descri ed.

The generator is provided with the usual type of'gas bell 20 that has its lower edges positioned in the water seal and the bell is vertically movable with respect to the tank. Secured in the upper end of the gas bell is a carbid hopper 21 which has its lower portion substantially cone-shaped with an open lower end. 'Positioned within the' carbid hopper 21 is a valve 22 that has a vertically movable stem 23 uided within the hopper 15 by brackets 24-. he lower end of the stem 23 projects downwardly below the open end of the hopper and has a weight 25 positionedon its extremity. The stem 23 is disposed in vertical alinement with the central portion of the branch inlet pipe 18 and the extremity of the stem is adapted for engagement with the'head 19 of this portion. The

, upper end of the carbid hopper is rovided W with an 'inlet which is used for fi ling the tions of the cross same. Projecting'upwardly from the top of the carbidhopper'21 is a vertically upright stem 26 which is slidably positioned through the cross coupling 16 of the cross pipe 15 that connects the upper ends of the service and outlet pipes. pon movement of the gas bell, this stem will slide within the" cross coupling and will act as a 'guidefor the bell and 110 per. An eye 27 is disposed on the end 0 the stem for a purpose to be hereinafter more fully described.

Projecting upwardly from one of the secpi e 15 is a standard 28 that has a lever end. This lever 29 is provided with. a hook 30 on one end and a handle 31 on the'other,

and the hook 30 is so disposed that it is adapted for engagement with the eye 27 on the stem 26. The fulcrumed lever 29 has an additional hook 32 which provides means whereby the lever may be locked in raised position. When it is desired to lift the gas bell and carbid hopper out of the tank, the fu lcrumed lever is lowered and the hook at the'end of the same is engaged with the eye olrtl e upper end of the stem. Upon raising the lever, the gas bell and hopper will be raised and they may be locked in this position by the locking means 32 on the lever.

t} 'lhehopper may then be busily filled with ,ai cdimas ends with a valve 35 which valve is operated by a crank 36. Projecting xlcrumed at its upper nection and owing to the fact that the valve 35 is normally closed, upon the hopper being elevated b the gas bell when an excessive amount 0 gas is formed in the bell, the hopper will consequently be raised to an u"= usual height and by the above described connection the crank 36 will be operated and the valve opened. The excess volume of gas may then escape through the transverse pipe 11, the outlet pipe 12 and off through a discharge 39 on said pipe. As soon as the gas'within the bell returns to normal, the bell and hopper will drop and the valve will return to closed position.

In operation, when the carbid hopper 21 a is full, the lower end of the stem of the valve will engage the head 19 of the verti cal gas inlet pipe, and the valve will be opened and the carbid fed into the water tank to generate the gas. As the gas forms within the bell, the same will rise slowly and when an excessive amount is placed therein, owing to the fact that the valve from the carbid hopper is held stationary by its weighted stem, when the bell and hopper rise, the flow of carbid will be ,cut'

off 'automaticnlly- This will prevent a further generation of gas until that within the tank has been carried 01f by the dischar e pipes. If, for any reason, t e valve shou dnot work and the as should still be eneratcd within the be 1, the same will rise to an excessive hei ht and the safety valve will be opened as as been hereinbefore described and the gas will not only be carried through the service pipebut it will also be carried out through the excess volume outlet pipe and discharged. 1

The agitator used 1n the water tank forms a very simple means for preventin g sediment from gathering in the ottom' thereof and owing to the fact that this tank is rovided with a' sloping bottom and an out et at its lower and, the same may be easily drained. The connected pipes that form the frame around the gas bell and hopper are of any proportional sizeand arejeonnected in any desired manner. These pipes are provided with plugs at the upper ends of the vertical pipes so that the gas will. not enter the up per cross pipe. The transverse pipe within the tank that is connected with the pipe 18 that is dis osed within the tank and bell, forms a ischargc and gas flows therethrough one way to the service pipe and the other to the excess volume pipe.

' From the foregoing description of the construction and operation of my improved acetylene gas generator, the manner of applying the same to use and the-operation thereof will be readily understood, and it will be seen that l have provided a simple and ellieient means for carrying out the ob jeets of the invention.
